Divided and this application filed-'May l yOur present applicationy is adivision of our application for Letter-s Patent for im` provements in vending machines Serial No. 80,940, andy the invention herein set forth consists in improved.coin-controlled mechanism for use in vconnection with vending machines and the like.V l

Fig. 6 isa fragmentary section on line V6 6, Fig. 3; .y 1,. y Fig. 7 is a sectional detail of the com chute; and Y f Fig. 8 shows the door latch. Briefly describing the vending machine shown, the same being fully Iset forth in detail in our aforesaid application: The case of the machine has two side walls l, a front wall 2 with an opening 2a therein, top and bottom Walls 3 and 4, top and bottom cross braces, 5 and 6, and a door 7k occupying the opening 2a and adapted to swing from closed to open position downwardly on a horizontal axis at its lower or pivoting edge. The case contains, suitably journaled in 5 and6 on a vertical axis, a semi-circular shield 9 and also, suitably pivoted therein, a tray or carrierl ll (Fig. 3)` which is pivvoted at l2 in the case and when the door is .open andthe shield is in the position shown in Fig. 2 will Vbe shifted in la horizontal plane forwardly through' the door opening and 'over the door, themeans whereby the door `and tray are connected to move together in this way-being vnot necessary to vdescribe herein in detail; l

Releasable locking means for theudoor is provided, the saine comprising the springheld latch 19, pivoted to front wall 2, which normally holds the door closed, and a manually rotated member for lmoving the latch clearof the door, this `membercomprising aspindle20y journaled in wall 2 and hav- ,ving an arm-202? to engage the latch and a knob 20h. This/means, however, cannot .be operated until the customer has deposited the proper coin or coins, as will appear.

The fiXed-npper portion 2lmof a coin-chute, L, whose intake opening is indicated at .21a in Figli, is provided at the back offrontwall 2, this discharging into another chute-por-v tion, as will-"appear, which is adapted to sup.-

vport temporarilya `coin in the positionindicated atpA in'Fig. 4 vso that said. coinin part occupies chute-portion 2l, which hasa a coin is present at A it intervenes between a cam 22 on spindle 2O anda pawl 23 pivpres'sed inward by a oted on apin 24 and spring 23a, said cam and pawl being received by the slot if'the lspindle is turned thecam,L

by `wiping against the coin, represses it` and to(k consequently the detentformed bythe pawl,

which thus permits the spindle to complete the movement necessary` to `movey the `latch and release the door. If no coin is present turning moveinent'of the spindle is then obstructed bythe detent or pawl. f Y

'The coin-controlledv controlling nism is constructed so 4 that the doory cannot (be -releasedunless a coin of'a predetermined size, asa nickel, is used" and av predeterlmined number of such coins'are deposited;

mecha-l provision is alsomade forI the return` of coins not earned. To these ends the fixed chuteportion 2l` debouches into a .lower :chuteportion formed in. part by a (normally) fixed plate 25 andin part by a channel-plate 26L adapted tof swing away from plate 25v on thev pin 24 as a pivot but normaliynrged vtoward the same by the yspring 232k Plate 25 has tapped into it at different elevations screws 27 whose inner ends are pointed (Fig.

7) and formstops for the-coins. We make use"ofthese stops for supporting'- al coin in the position A, and'accor'ding as one, two,

locking the door-latcli-releasing means the vthree or'ffour coins-'are necessary for un` iirst, second, third or fourth stopis screwed fully in and the rest are screwed back or [withdrawn (except, as .will appear, the

fourthl or lowest stop is always screwed in). rihe channel-plate 26 has at the back, opposite the lowest screw 27, an outlet 26, Figs.4 3 and 6, arranged at the same level as the upper or cam-inlet end of an "inclined chute 28 which discharges into a coin-box 29. In the normal position of the channelplate' this outlet fis opposed. by the inner wall of the chute28 sothat n0 Coinvcould'- ,y
